Sprinkler System Basics
The three main components of every automatic sprinkler
system are the controller, station control valves and
sprinklers.
The controller is the brain of the system, telling the control
valves when and how long to supply water to the sprinklers. The sprinklers direct and control the water applied to
the lawn and plants.
Each valve controls a specific group of sprinklers called
a watering station. The stations are generally laid out
and installed according to the type of plant material to be
watered, the location of the plant within the landscape
and the maximum amount of water which can be supplied. Each valve is connected to a numbered terminal
within the controller, identifying it as Station 1, Station 2,
etc.
The controller operates the valves in order, one at a
time. In other words, one station would water completely
before another station would turn on. This is called a
watering cycle. The information stored in the controller
memory which determines when and how long the stations will water is called a program.
The next section of this guide is very important. It explains
what a program is and how the GreenKeeper 212 controls
the operation of the sprinkler system.

Watering Program Basics
A watering program requires three basic instructions to
operate automatically:
• What days to water –called watering days
• When to water – called a program start time
• How long to water – called station run time

Watering Program Diagram
Program
Starts - 5:00 AM
Station 1

The following example illustrates how a typical watering
program could be set for the sprinkler system shown on
the previous page.
Example: The program start time is set for 5:00 AM. Lawn
stations 1 and 2 each have a run time of 10 minutes and
lawn station 4 is set to run for 20 minutes. Note that stations 3 and 5 water shrubs and flowers and have been
excluded from this program. (These stations will be set
to operate on separate programs).
As shown in the watering program diagram, at 5:00 AM
the controller starts the program watering cycle. Station
1 sprinklers run for 10 minutes and shut off. Station 2
sprinklers turn on, run for 10 minutes and shut off. The
controller skips station 3 and turns on station 4, which
runs for 20 minutes and shuts off. Station 5 is skipped
and the watering cycle ends at 5:40 AM.
As you can see from this example, only one program
start time was needed to operate three different stations.
Because of variations in plant watering needs, the
GreenKeeper 212 provides three separate programs.
The programs, called A, B and C, are completely independent of one another – like having three timers in one
housing.

Station 2

Station 4

Program
Ends- 5:40 AM

Using more than one program for example, would enable
lawn zones to be watered every day on program A,
shrub zones to run on on Monday, Wednesday and Friday on program B and drip irrigation to soak the flower
beds every three days on program C.
Although the GreenKeeper 212 offers the multiple program feature, you may want to have all zones on one
program if it meets your needs. The other programs can
remain turned off until you need to use them.

Watering Program Details
This section covers in detail each of the three parts of a
watering program – watering days, program start times
and station run times.

Selecting Watering Days
The GreenKeeper 212 provides four options for scheduling watering days: Calendar, Interval, Odd or Even and
Off.
Calendar Schedule
A Calendar schedule enables you to select specific days
of the week to water, for example, Monday, Wednesday
and Friday. This is a seven-day schedule which starts on
Sunday and ends on Saturday.
This illustration shows how a Calendar schedule would
be displayed when the control dial is in the
WATERING DAYS
position.
In this example, program A
has watering days set for MO
(Monday), WE (Wednesday)
and FR (Friday).

This illustration shows how
an Interval schedule would
be displayed. In this example, program B has a 3-day
Interval schedule which will
start on Monday.

PGM A B C

SU MO TU WE TH FR SA

Odd/Even Schedule
The Odd/Even schedule enables you to select odd or
even numbered days of the month as watering days.

This illustration shows how
an Odd day schedule
would be displayed.

PGM A

Program Off
PGM A

SU MO TU WE TH FR SA

Interval Schedule

you can choose which day of the week will be the first day
of the Interval. The number of days in the Interval determines the available start days. For example, if you have
selected a 3-day Interval and today is Sunday, you may
choose to start the Interval today, Monday or Tuesday.

An Interval schedule enables you to set watering days
without regard to the actual days of the week. For example, if you want to water every third day, you would
select a 3-day Interval. Interval schedules range from
1-day (watering every day) to 7-day (watering every seventh day). Once you have selected an Interval schedule,

Selecting OFF suspends the operation of the program
when it is not needed. Turning the program off does not
alter or erase the watering day schedule of the program,
it simply places the program on hold until it is needed.
This illustration shows how a
program would be displayed
if its watering day schedule
is turned off. In this example, program C is off.

Selecting Program Start Times

Setting the Station Run Time

A program start time is the time of day you select to
begin an automatic program watering cycle.
It is important to remember that a program only
requires one start time to operate automatically.
When a program starts, each station assigned to the
program will water in numerical order, one at a time for
its set run time.

A station run time is the length of time the station (controlled by the valve) will water during the program watering cycle. The run time for each station can be set from
Off (no run time) to 4 hours, in one-minute increments.

Sometimes it is necessary to run a watering program
more than one time per day. For example, when growing
a new lawn. The GreenKeeper 212 enables each program to have up to four separate start times per day.
Program start times are numbered 1 through 4. These
numbers are shown at the top left of the display next to
the start time symbol
when the control dial is in the
PROGRAM START TIME
position and indicate how
many start times are currently set for the program.
This illustration shows how
a program start time is
displayed. In this example,
program A has one start
time (start time number 1)
set for 5:00 AM.

A station is assigned to a program when it is given a run
time. If the run time for a station is turned Off in a program, it will not operate during the program watering
cycle. This is how the GreenKeeper 212 enables you to
assign stations to different programs.
All stations assigned to the program are shown on the
lower portion of the display when the control dial is in the
STATION TIMES
position.
This illustration shows how
a station run time is displayed for a program. In this
example, zones 1–6 are
assigned to program A.
Station 1 has a 10-minute
run time and station 2 is set
to run for 25 minutes.
The station run time being
displayed is identified by the
flashing station number.

Planning Your Watering Schedule
It is always helpful to plan your watering schedule on
paper before beginning the programming steps. You will
have a record of your watering schedule and station locations which can be kept with your GreenKeeper 212 after
it is installed. If you have an indoor model controller, a
watering schedule form is provided on page 12 for you to
fill out then remove to keep with the controller. This form is
duplicated on a decal located on the inside cover of the
outdoor model.
◆ Guidelines for Watering

There are several factors to be considered when deciding when and how long to water. For example, the soil
type (i.e., clay, loam, etc.), the part of the landscape
being watered, climate conditions and the type of sprinklers being used. Because of these variables, we cannot
provide an exact schedule to follow, but here are some
general watering guidelines to help you get started.
• Water early in the morning, one to two hours before
sunrise. You will have the best water pressure at this
time and the water can soak into the plant root zone
while evaporation is minimal. Watering during mid-day
or in the evening may cause plant damage or mildew.
• Watch for signs of under- or over-watering and make
program adjustments immediately.

Filling Out the Watering Schedule Form

When filling out this form, use a pencil so changes can be
easily made. After installing the indoor model controller,
remove the form and store it in the pocket formed

between the mounting bracket and the back of the controller housing.
Refer to the example form shown on the opposite page
and fill out your form in a similar manner with the following information:
• Location - Identify the location of each watering station and the type of plant being watered.
Note: Enter the following information for each program. If the program is not needed, leave its information column blank.

•

Watering Day Schedule - For a Calendar schedule,
indicate which day(s) of the week watering is desired.
For an Interval schedule indicate the desired Interval
number. For Odd or Even days, simply mark the
appropriate box.

•

Station Run Time - Indicate the amount of run time
(1 minute to 4 hours) for each station. Write “Off” for any
station which you do not want to operate in the program.

• Program Start Times - Indicate the time of day to
start the program. Each program can have 1 to 4 start
times per watering day.
Note: The GreenKeeper will run only one watering
cycle at a time. Therefore, when using multiple start
times within a program or when using multiple programs, make sure that each watering cycle will be
able to run completely before the next watering cycle
is scheduled to start. A program start time that occurs
while a watering cycle is in progress will be delayed
until the current watering cycle is finished.

Programming Before Installation
The GreenKeeper 212 utilizes a 9-volt battery to retain its
watering program information in the event of a main power
interruption. This battery backup feature also enables
your controller to be fully programmed for operation right
out of the box—before installation—in the comfort of your
home. Simply attach the battery and begin the programming steps. The program information will be retained for
the duration of the battery life – about 72 hours for an
Alkaline battery or 24 hours for a rechargeable NickelMetal Hydride (Ni-MH) battery.

Installing the Battery
Note: The 9-volt battery does not supply enough voltage
to operate the station control valves.
1. Indoor models: Slide the lower housing cover toward
the bottom of the controller to remove.
Outdoor models: Pull outward on the lower housing
cover handle to remove.
Locate the battery wire clip and attach it to the battery
terminals. Place the battery into the cabinet compartment as shown in Figure 1.
Figure 1

2. The display will begin flashing 12:00 AM. Press the
+/ON button to stop the display from flashing. The
colon (:) will continuously flash while displaying the
time and during watering operation. The Power Off
symbol
will be displayed until the main power
supply is connected.
3. Locate the battery charger
Figure 2
switch (9) as indicated in
Figure 2. If an Alkaline battery is installed, the switch
must be set to the left position (ALK) to turn the
charging circuit off. If a
9
rechargeable Ni-MH battery
is used, the switch must be
set to the right position
(RCHG) to turn the charging circuit on.

BATTERY

Caution: The battery charger switch must be set
correctly. Damage to the controller can result from
an Alkaline battery which may fail if charged.
4. Reinstall the lower housing cover.
WARNING:
Always replace battery with the same or equivalent
type. Dispose of used batteries according to the
battery manufacturer’s recommendations.

Selecting Optional Features
24-Hour Clock Mode
The GreenKeeper 212 is
set to display time in the
12-hour clock mode. If you
prefer to use a 24-hour
clock mode (military time),
select this option by removing the 12/24 Hour Selector
Jumper (5). To store the
jumper, install it on one pin
as shown. See Figure 3.

Figure 3

BATTERY

15-Second Run Delay
The 15-second run delay feature is useful for sprinkler
systems utilizing a pump or master valve. For example,
a pump usually requires a few seconds to build pressure
after first starting. With the 15-second run delay selected, the pump would be running (or the master valve
would open) 15 seconds before the first station begins
watering. A 15-second delay would also occur between
station operations. This helps ensure that one valve is
closed before another valve opens.
Note: A 2-second run delay will occur if this option is not
selected.
To select the 15-second delay option, remove the Delay
Selector Jumper (6). See Figure 3.
Odd/Even Watering Days

If you plan to use an Odd/Even day watering schedule,
remove the Odd/Even Selector Jumper (7) for this option.

About the GreenKeeper 212 Memory
The GreenKeeper 212 has a permanent watering schedule within its memory to assist you in two ways. First, it
will restore watering operation in case your watering program is lost due to a power interruption lasting longer
than the battery backup reserve. This prevents your
landscape from going unwatered if the power outage
occurs while you are away.
Secondly, if you do not want to program your
GreenKeeper 212, you can use the permanent watering schedule to operate your sprinklers. Just set the
current time and day and your GreenKeeper 212 will
be ready to operate automatically.
The permanent watering schedule operates as follows:
When power is applied, the controller clock is set to
12:00 AM Sunday. Program A has a Calendar watering
schedule set to water every day. One program start time
is set for 5:00 AM (5:00) and a run time of 10 minutes is
set for each station. Programs B and C are turned Off
and have no program start times or run times.
Note: An optional feature is provided which enables the
The GreenKeeper 212 memory to be reset to the permanent program or cleared completely if you choose. If you
do not want to use this option, skip the next procedure
“Resetting The Controller Memory” and continue at page
16 to begin programming.

Resetting the Controller Memory
The GreenKeeper 212 program memory can be reset to
the permanent program values or cleared completely at
any time without removing power.

Figure 4
2

Resetting the permanent program erases all user input
and replaces it with the permanent program values.
Clearing the program memory sets all program values to
Off (i.e., no active days, program start times or station
run times). You may find that this simplifies programming
the controller if your watering requirements are quite
different than the permanent values.

Connecting a Toro Rain Switch
(Optional)
The Toro Rain Switch is a remote rain sensor which can
be connected directly to your GreenKeeper 212 to automatically interrupt watering during rain.
A sensor bypass switch is provided which enables the
Rain Switch operation to be turned On and Off.
When the Rain Switch absorbs rain water it automatically
signals the GreenKeeper 212 to suspend all watering
operations. The “No Watering” symbol will appear in
the upper right corner of the display until the Rain Switch
drys out and automatically resets. The “No Watering”
symbol will disappear and controller operation will
resume as programmed.

Note: The Toro Rain Switch is a normally closed
device. To install a normally open Rain Switch,
refer to the instructions provided with the device and
and install accordingly.

Controller Operation
The GreenKeeper 212 controller has three modes of
operation: Automatic, Manual and Off. In the Automatic
mode the controller tracks the time and day and operates the automatic watering schedules. The Manual
mode enables the watering programs to be started and
controlled manually at any time. The Off mode shuts off
all watering activity and prevents any zones from operating automatically or manually.
The Rain Delay and Season Adjust control features are
provided to enable quick, temporary changes in operation
to help compensate for variables in weather and season.
Each of the operating modes and control features are
explained in this section of the guide and can be found
on the following pages:

Automatic Operation

In the Automatic mode, the GreenKeeper 212 keeps
track of the current time, day of the week and the automatic watering program schedule. Automatic operation
will occur whenever a programmed watering day and
start time match the current time and day.

The Automatic mode is selected when the control dial is
in the RUN position. While in the automatic mode, the
display will show two types of information:
status and operation.
This illustration shows the
status display. In this
example the current time is
2:45 PM and the current
day is Monday. Programs
A and B are active on Monday.

When watering starts, the operating display appears and
is shown for the duration of the program.
In this example, program A
is operating. Station 1 is
watering and has 10 minutes of run time remaining.
Zones 2, 3 and 4 will operate during this program.
Program B is also programmed to run today.

Flashing

Note: If the control dial remains in any other position
(except OFF) for more than 8 minutes, the controller
reverts to the Automatic mode.
Note: The position of the PROGRAMS switch does not
determine which program will run during automatic controller operation. In other words, if a program has an
assigned watering day schedule, start time and a station
with run time, it will operate automatically regardless of
the position of the PROGRAMS switch.

Manual Operation
Manual operation enables the automatic watering programs or selected stations assigned to the program to be
started manually. During operation, temporary changes
can be made to increase or decrease the station run
time, step through the station sequence and pause or
stop watering using the “Watering Control Features”
described on page 32. Upon completion of the manual
watering operation, the controller will return to the Automatic mode.

Starting Programs and/or Stations Manually
You may operate all stations or selected stations in each
program. Watering programs can be started individually or
set to start in order. When one program finishes the next
selected program will operate.
Ensure the control dial is in the RUN
position.
Position the PROGRAMS switch to select the program
you wish to start.
Choose one of the following manual operations:
• To operate the selected program with all
assigned stations, press the MANUAL START
button two times to begin watering.
• To operate only selected stations, press the
MANUAL START button, then press the +/ON button
to select the flashing zone number, or press the
–/OFF button to skip the zone number. Continue
selecting or omitting zones in this manner. When
only the desired zones are displayed, press the

The following watering control features enable you to further control the watering program during operation.
All watering control features apply to watering programs
started manually and automatically.

To Pause Watering

To Cancel Watering
Press the +/ON and –/OFF buttons at the same time two times.
• All watering operations will be canceled and the controller will return to the automatic mode.
Note: Placing the control dial in the OFF position for
two seconds, then back to RUN
will also cancel all
watering operations.

Press the +/ON and –/OFF buttons at the same time.
• The station currently watering will shut off.

To Skip Stations

• The “Watering On” symbol will begin flashing.

Press the NEXT button one time.

• The display will show the amount of run time remaining for the paused station.
Note: If watering is not resumed within 8 minutes, all
watering operations will be canceled and the controller will return to the automatic mode.

• The station currently watering will shut off and the
next station will start.
• If the last station is skipped, the program will end. If
additional programs have been set to operate, the
next program in alphabetical order will start.

To Resume Watering (when paused)

To Adjust the Station Run Time

Press the NEXT button.

Press the +/ON button to increase run time or the –/OFF
button to decrease run time.

• Watering activity will resume from the point of interruption.

• If the station run time is decreased to less than
1 minute, the station will shut off. The next station in
sequence will start.
• The station run time is changed during this operation
only. The program memory will not be changed.

Turning Off the GreenKeeper 212
Flashing

When the control dial is turned to the OFF position, the
controller immediately shuts off any watering operation
currently in progress. Leaving the control dial in the
OFF
position will prevent all automatic and manual
watering operations. The controller will continue to track
the current time and day of the week.

For extended shutdown of the sprinkler system leave the
control dial in the OFF position.
The word OFF will be displayed
for 8 minutes. The automatic status display will then appear.

Automatic operation is resumed
by turning the control dial to the
RUN
position.

Using the Rain Delay Feature
This feature enables all watering operations to be
delayed from 1 to 7 days. For example, rain is forecast in
your area for the next two days. Instead of turning the
controller off (and possibly forgetting to turn it back on), a
rain delay of 3 days can be easily entered. At the end of
3 days, the controller will resume automatic operation as
scheduled.

Turn the control dial to the RAIN DELAY
position.
The rain delay display will begin alternating with the
automatic status display.
To set the number of rain delay days, press the +/ON
or –/OFF button until the desired number (1–7) is
flashing.
Return the control dial to the RUN

position.

Note: The rain delay number will automatically
decrease as each day passes. When the number
reaches 0 (zero), automatic operation will resume at
the next scheduled start time.
To cancel the rain delay, turn the control dial
momentarily (3 seconds) to the OFF position.

Using the Season Adjust Feature
Changes in season and temperature generally require a
change in station run time to maintain a healthy landscape and conserve water. The season adjust feature
enables you to change the run time of all zones assigned
to a program, simultaneously up or down, in 10% increments – with just the press of a button. Adjustments can
be reduced to 10% or increased to 200% of the programmed run time of each station.
A 50% setting, for example, would decrease a 20-minute
station run time to 10 minutes. Increases however, work
a little differently. With any adjustment above 100%, the
GreenKeeper 212 will first increase the run time by the
adjustment percentage, then split the time in half and run
the watering program twice. This allows the water to
soak in instead of pooling or running off. For example,
adjusting to 150% would first increase a 20-minute station run time to 30 minutes, then split the time in half and
run two watering cycles back-to-back with 15 minutes in
each operation. During operation the % symbol will flash
to indicate a multiple watering operation.
Note: All station run times are retained in the controller
memory and returned to their set value when the season
adjust is reset to 100%. The only time a station run time
will appear changed is during operation.
